Highest temperature in Shanghai on August 6?

Platform comparison

Market context

Shanghai’s outcome depends on the highest temperature recorded at Shanghai Pudong International Airport on 6 August, using Wunderground’s daily history page for the airport station. The live market already implies **0% YES**, which is consistent with a contract whose settlement is tied to a single station observation rather than a city-wide average: traders are effectively pricing the chance that the day’s recorded maximum lands in the relevant Celsius band, not whether Shanghai feels hot overall. Recent forecasts point to a hot, humid afternoon, with one source showing about 35°C and another showing highs in the low-to-mid 30s Celsius, though actual settlement depends on the airport station reading rather than forecasted city conditions.[1][2][4][8]

For context, Shanghai in August typically sits in the low 30s Celsius, with humidity, showers and occasional thunderstorms common, so comparable summer weather markets often resolve around the forecast range rather than an outlier spike. Current observations already show very warm conditions across Shanghai, including readings near 91°F/33°C at other stations, which supports the idea that the day’s maximum could cluster around the mid-30s Celsius if cloud and rain do not suppress the peak.[14][15][16][19] Under German GlüStV rules, markets accessible to German residents can trigger gambling-law scrutiny if they are treated as games of chance rather than pure information contracts; that matters because even a weather market can be assessed on access and promotion, not just subject matter. In the US, CFTC reach is most relevant where a contract may be viewed as a derivatives-style event market, so venue, user location and product design remain part of the regulatory picture.

For accessibility, “no-KYC up to $1,500” means a user can usually trade without identity verification until cumulative activity or withdrawals cross that threshold, but it does not remove geoblocking, sanctions screening or local-law limits. For this market, that makes participation easiest for smaller accounts, while larger positions may require verification before limits are lifted. The practical catalysts are the daytime heating curve, any sudden rain or thunderstorm bands over Pudong, and whether the airport station’s official observation captures a brief spike before cloud cover or precipitation sets in.[2][13][14]
